sPECIFICATION forming part of Letters Patent No. 288,823, dated August 2?, 1883,

A pplieation filed November 29, 1882. (No model.)

To all ZU7L0777/ it may concern:

Be it known that I, GEORGE XV. Sn'AM'P, a citizen of the United States, residing at Buffalo, in the county of Eric and State of New York, have invented certain new and useful.

Improvements in FeedWVater Heaters and Purifiers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to thereby heated and purified; and it consists,

broadly, in means for forcing the reed-water into the steai'lrpassage from the inner circumference of such steam-passage toward its center, wherein it meets the incoming steam, and is forced with such steam into the body of the heater through the unobstructed steam'pas sage.

In the drawings, Figure 1 is an elevation of a :t'cedwater heater and purifier, partly in section, and with portions broken away to show my improved construction. Fig. 2 is an enlarged top plan view of my improved oom mingling device, partly in section. Fig. 3 is a sectional elevation of a modified form of comminglingchamber. Fig. 4 is a sectional. de tail view taken in the line 00 00 of Fig. l, and Fig. 5 is a sectional, detail view taken in the line 2 y of Fig. 1.

Referring to the drawings, a. is the cylindrical body 01' the heater, across the flanged top of which is secured the cover a, provided with usual arm-hole, 7), and exhaust-pipe b.

To the flanged bottom of the cylindrical por tion a is secured the inverted cone-shaped bot tom 0, having the outlet 0 located at its apex. In this outlet is secured the globe-valve 0 which permits of the discharge of the impurities collected in the bottom of the heater.

0" is an arm-hole in the side of the portion 0, and (Z is the outlet-pipe which conveys the heated and purified water to the boiler.

. 1 The parts thus far described are of ordinary construction and arrangement, and form 110 part of my invention.

I will now proceed to describe the simplest form in which I have thus far constructed my improved eommingling-chamber, it being un derstood that it is susceptible of considerable variation without departing from the broad spirit of my invention, which consists, as before stated, in forcing the feed-water in the form of a spray or sheet from the inner circumference of the steam-passage toward its center.

I have preferably located my improved comminglingchamber upon or near to the top plate, a, of the heater. It consists of an annular chamber or passage, 0, having the opening (2, into which the pipe j, which conducts the water to the heater, is secured. This annular chamber 0 is provided with. the flange g, by means of which it is secured by the bolts 9 to the top plate, a. Extending from the chamber a downwardly through an opening.

in the top plate, a, is the pipe 71 which forms a continuation of the steam-passage, and is of 7 5 a diameter equal to the inner diameter of the annular chamber 0. h. is a circular screwthreaded extension above the annular chamber c, and in line with the pipe 71 Into this extension is securedthe pipe In, which carries the exhaust-steam from the boiler to the heater. This steam-pipe 7r: preferably of the same diameter as the pipe 71 and it will thus be seen that the passage through which the steam passesinto the heater is entirely unobstructed. The curved inner surface of the annular chamber 0 provided along its entire circumference with a series of holes or perforations, Z, opening into the steam-passage; but instead of these holes Z a series of narrow slots might be made. The holes I are preferably inclined upwardly, as shown in Fig. 1.

The operation of the commingling-chamber just described is as follows: The water to be heated is admitted through pipe f into the an-. nular chamber 0, surrounding the steam-passage, and passes through. the holes or perforations Z into the steanrpassage in an upward direction in the form. of a spray or sheet, as clearly shown at m, Figs 1 and 2, where it water are admitted to the heater in a direct and unobstructed manner, and the water is thoroughly and quickly heated and purified. It might be found advantageous in some instances to locate the annular water-chamber e, surrounding the steam-passage, at some distance above or away from the heater, and to have the sprays or sheets of water thrown into the steam-passage both in an upward and downward direction. Ihave therefore shown in Fig. 3 a modification applicable to the above-named requirements, in which I have omitted the cylindrical'extension h and rounded off the lower edge of the opening, as shown at 0 0, providing at the same time additional perforations, Z, by means of which, with the perforations Z, the water is thrown into the steam-passage both in an upward and downward direction, as clearly shown in dotted lines. Its flange 9 adapts it to be secured to a corresponding flange in the exhaust-steam pipe at any point I claim 1. In a feed-water heater and purifier, an unobstructed steam-passage leading into the body of the heater, such steam-passage being surrounded by a water-chamber communicating with the interior of the steampassage, whereby thewater is admitted to such steampassage from its'inner circumference, substantially as shown and described.

' 2. In a feed-water heater and purifier, the commingling device, consisting, substantially, of the annular chamber 6, surrounding the steam-passage, and having theopening 6, through which the water is admitted,- and the perforations Z, through which the water is thrown from the inner circumference of the steam-passage toward its center to meet the incoming steam, the annular chamber e being connected with the exhaust-steam pipe and with the heater, substantially as shown, so

that the commingled steam and water passes into the heater through an unobstructed passage, substantially as shown and described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
